The historical province of Picardy stretched from north of Noyon to Calais, via the whole of the Somme department and the north of the Aisne department. The province of Artois (Arras area) separated Picardy from French Flanders.

The name "Picardy" (which may have referred to a Frankish tribe of picards or pike-bearers) was not used until the 12th or 13th century. During this time, the name applied to all lands where the Picard language was spoken, which included all the territories from Paris to the Netherlands.[3] In the Latin Quarter of Paris, people identified a "Picard Nation" (Nation Picarde) of students at Sorbonne University, most of whom actually came from Flanders.[4] During the Hundred Years' War, Picardy was the centre of the Jacquerie peasant revolt in 1358.

In the 16th century, the government (military region) of Picardy was created. This became a new administrative region of France, separate from what was historically defined as Picardy. The new Picardy included the Sommedépartement, the northern half of the Aisnedépartement, and a small fringe in the north of the Oisedépartement.

In the 17th century, an infectious disease similar to English sweat originated from the region and spread across France. It was called Suette des picards or Picardy sweat.[5]

Sugar beet was introduced by Napoleon I during the Napoleonic Wars in the 19th century, in order to counter the United Kingdom, which had seized the sugar islands possessed by France in the Caribbean. The sugar industry has continued to play a prominent role in the economy of the region.[6]

One of the most significant historical events to occur in Picardy was the series of battles fought along the Somme during World War I. From September 1914 to August 1918, four major battles, including the Battle of the Somme, were fought by British, French, and German forces in the fields of Northern Picardy.[7]

In 2009, the Regional Committee for local government reform proposed to reduce the number of French regions and cancel additions of new regions in the near future. Picardy would have disappeared, and each department would have joined a nearby region. The Oise would have been incorporated in the Île-de-France, the Somme would have been incorporated in the Nord-Pas-de-Calais and Aisne would have been incorporated in the Champagne-Ardenne. The vast majority of Picards were opposed to this proposal, and it was scrapped in 2010 (see newspaper: "Courrier Picard").

Between the 1990 and 1999 censuses, the population of Oise increased 0.61% per year (almost twice as fast as France as a whole), while the Aisne department lost inhabitants, and the Somme barely grew with a 0.16% growth per year. Today, 41.3% of the population of Picardy live inside the Oise department.

Picardy stretches from the long sand beaches of the Somme estuary in the west to the vast forests and pastures of the Thiérache in the east and down to the chateaux of Chantilly or Pierrefonds near the Paris Area and vineyards of the border with Champagne (Champagne picarde) to the south.

Historically, the region of Picardy has a strong and proud cultural identity. The Picard (the local inhabitant and traditionally Picard language speakers) cultural heritage includes some of the most extraordinary Gothic churches (Amiens and Beauvais cathedrals or Saint-Quentin basilica), distinctive local cuisine (including ficelle picarde, flamiche aux poireaux, tarte au maroilles), beer (including from Péronne's de Clercq brewery) and traditional games and sports, such as the longue paume (ancestor of tennis), as well as danses picardes and its own bagpipes, called the pipasso.

The villages of Picardy have a distinct character, with their houses made of red bricks, often accented with a "lace" of white bricks. A minority of people still speak the Picard language, one of the languages of France, which is also spoken in Artois (Nord-Pas de Calaisrégion). "P'tit quinquin", a Picard song, is a symbol of the local culture (and of that of Artois).

Picardy is the birthplace of Gothic architecture, housing six of the world's greatest examples of Gothic cathedrals, which envelop the history of Gothic architecture in its entirety. Amiens Cathedral, standing as the largest cathedral in Europe, which according to John Ruskin is the "Pantheon of Gothic architecture", could house the Notre-Dame de Paris twice over. It was built in as little as 50 years. Picardy also holds the tallest transept in the history of the Gothic period located on Saint-Pierre cathedral in Beauvais, Oise.

The Museum of Picardy, built between 1855 and 1867, houses a vast array of great works, spanning centuries. Archaeology from ancient Greece and Egypt to works of Pablo Picasso. The museum was built for the very reason it is used today. Although Picardy is one of the least-known regions in France, its influence from art and most certainly architecture is vivid throughout the world.[9]
